| 01:46 | < [R]> | How's that one specifically work? |
| 01:46 | <&Derakon> | I'd guess it's an unsigned int, since I can't see anything else really making sense as a default type. |
| 01:46 | <@celticminstrel> | Yeah. |
| 01:46 | < [R]> | Does it just cast to a fixed size or does it keep the size? |
| 01:46 | <&Derakon> | It does seem like an under-named function though. |
| 01:47 | <@celticminstrel> | No, it's the same as (unsigned int)x |
| 01:47 | <@celticminstrel> | If you omit the size, an integer is implicitly int size. |
| 01:47 | < [R]> | Is it actually a function? What header has the prototype? Or is it just alternate syntax for the type casting system? |
| 01:47 | <@celticminstrel> | So, "signed", "signed int", and "int" are all the same type; similarly, "unsigned" and "unsigned int" are the same type. |
| 01:48 | <@celticminstrel> | It's not a function. |
| 01:48 | <@celticminstrel> | It's an alternate syntax for casting in mimicry of constructor notation. |
| 01:48 | < [R]> | So it works with UDTs then, like uint64_t |
| 01:48 | <@celticminstrel> | It works with anything except multi-token types. |
| 01:49 | <@celticminstrel> | If you made a typedef of unsigned int, it would work with that. |
| 01:49 | < [R]> | That's what a User Defined Type is yeah. |
| 01:49 | <@celticminstrel> | It works with classes, in which case it's a constructor call. |
| 01:50 | <@celticminstrel> | It works with enums too. |
| 01:50 | | * [R] forgets if unions can have member functions and constructors too. |
| 01:51 | <@celticminstrel> | I don't remember either, but personally, I think the best use of unions is an anonymous union nested in another structure. |
| 01:51 | < [R]> | (C++ class's and struct's are the same thing apparently, just different default permission levels) |
| 01:52 | <@celticminstrel> | Yes. |

| 02:01 | < [R]> | g++ seems to treat unions the same. |
| 02:23 | <@celticminstrel> | Hm? |
